Benefits of technology

The invention is a guiding device for administering an injection of anesthesia in the vicinity of an inferior alveolar nerve in a subject. The device comprises a retro-mandibular tip and a guide unit or guide tube that hold the syringe. The guide tube has a stopper mechanism that stops the needle of the syringe at a predetermined point in its advancement. The device can be held in place on the facial region relating to the mandible and the syringe can be inserted through the guide tube and the injector administered to the desired location. The technical effects of the invention are to provide a reliable and safe method for administering anesthesia near the inferior alveolar nerve, which can reduce the risk of complications and improve the accuracy and effectiveness of the injection.

Problems solved by technology

However, upon its penetration into the soft tissue, the needle may bend, deflect, or slide along the pterygomandibular fascia thereby changing the trajectory imposed by the device.
An injection into the parotid space may result in a temporary paralysis of the facial nerve.

a Guiding Device for Inferior Alveolar Nerve Block

[0049]The availability of several techniques for inferior alveolar nerve analgesia in a targeted area of the pterygomandibular space reflects the difficulties faced by practitioners. The objective of this study was to design a guiding device for inferior alveolar nerve block. An analysis of 40 CT scans of facial masses aided in the determination of the most appropriate configuration of the guiding device. Depending on individual morphological characteristics, the projection point of the device was situated on the medial surface of the mandibular ramus, between 7.0 mm and 14.0 mm anterior to the posterior edge of the ramus.

Abstract

The invention provides a device for the practice of oral medicine, including dentistry. Specifically, the invention relates to a guiding device that helps to prevent injecting beyond the pterygomandibular space during inferior alveolar nerve block for which purpose the injection is administered in the vicinity of the inferior alveolar nerve. The device has a retro-mandibular tip (12) operably linked to a guide tube (14) by a connecting unit (20, 22, 24), the guide tube (14) is adapted to receive a syringe and has a stopper mechanism (19) to stop the advancement of the syringe such that its needle is located at a predetermined distance from the posterior edge of the mandibular ramus.

Description

PRIORITY CLAIM[0001]This is a U.S. national stage of application No. PCT / IB / 2015 / 000699, filed on Feb. 27, 2015. Priority is claimed on U.S. Provisional Application No. 61 / 945,499, filed Feb. 27, 2014, the content of which is incorporated here by reference.FIELD OF THE INVENTION[0002]The invention relates to a device for the practice of oral medicine, including dentistry. Particularly, the invention relates to a guiding device for administering an injection of anesthesia in the vicinity of an inferior alveolar nerve. More particularly, the invention relates to a guiding device that helps to prevent injecting beyond the pterygomandibular space during inferior alveolar nerve block.BACKGROUND OF THE INVENTION[0003]The inferior alveolar nerve is unusual in having a passage inside the mandibular bone, protected by a cortical layer. Inferior alveolar nerve block (IANB) is the preferred anesthetic technique for dental and oral surgery procedures, involving the infiltration of the nerve bef...
